Answer: Hello dear. You should limit how much you eat of these fish to two portions a week. Shark, swordfish and marlin contain much higher levels of mercury, so you shouldn't eat these fish at all while you're pregnant. Instead, you can eat as much as you want of any of the following salmon, tilapia, shrimp, tuna (canned-light), cod, and catfish. You can also confirm this with your doctor before consuming.
Answer: Hi. Yes but always check with what fish you are having. As some fish contains high amount of mercury which need to be avoided.
Also semicooked or half cooked fish is a big no. So make sure your fish is cooked properly.
